Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an improvement of an outlet mode control device for controlling an outlet mode of an air conditioner for a vehicle.

(Prior Art) An automobile in recent years is equipped with an air conditioner called a so-called fully automatic air conditioner that automatically air-conditions the interior of the vehicle according to the temperature of the outside air or the like.

Such an air conditioner is arranged in each part of the vehicle,
Based on various signals from various sensors that input temperature information related to air conditioning in the passenger compartment and various setting switches that input passengers' requests for that air conditioning, the temperature of air supplied to the passenger compartment, the amount of this air blown, and its air Select the outlet that blows out into the passenger compartment and automatically set the outlet mode. The interior of the vehicle is optimally air-conditioned.

Then, such various setting switches may be provided on the operation switch panel 1 as shown in FIG. 5, for example.

The operation switch panel 1 is provided with a room temperature setting switch 2 for setting the temperature in the passenger compartment, and the occupant operates the room temperature setting switch 2 to set the temperature in the passenger compartment to the temperature displayed on the display 3. You can set the temperature,
The air conditioner calculates the target outlet temperature of the air blown into the vehicle compartment in order to bring the temperature inside the vehicle compartment close to this set temperature,
The temperature of the air is adjusted based on the target outlet temperature, and the outlet that blows out the air is selected according to this adjustment, and the outlet mode is automatically set.

This outlet mode is, for example, a vent mode that sets a vent outlet that blows the air directly onto the occupant, a foot mode that sets a foot outlet that blows below the occupant's feet,
And a bi-level mode in which the air is blown out from these vent outlets and foot outlets, and the air conditioner automatically sets these outlet modes to effectively air-condition the vehicle interior. It has become.

Further, the operation switch panel 1 is provided with an outlet switch 4 for manually setting the outlet mode when the outlet mode automatically set by the air conditioner does not suit the passenger's preference. Each time the occupant turns on the air outlet change-over switch 4, the air outlet mode is switched in a preset order, and the air outlet mode required by the occupant is set.

(Problems to be solved by the invention) However, in such an air conditioner,
As described above, when the air outlet mode is manually set, the air outlet mode is switched in a preset order each time the air outlet changeover switch 4 is turned on. There is a problem in that the blower outlet changeover switch may have to be operated once, and such an operation is complicated, and it takes time to set the required blower outlet mode.

For example, if the outlet mode is preset to switch from vent to bi-level to foot, let the outlet mode that was automatically set to vent mode be the foot mode with the outlet switch. Then, the occupant had to turn on the outlet changeover switch twice.

Also, when the outlet switch is turned on, the first outlet mode is always set to the vent mode, so unexpected air temperature and air volume directly hit the occupant, causing temporary discomfort to the occupant. I had something to remember.

The present invention was made in order to solve such a conventional problem, and the initial mode of the manually set air outlet mode is set to the target air outlet temperature calculated when automatically air-conditioning the passenger compartment. It is an object of the present invention to provide an air outlet mode control device for an air conditioner for a vehicle, which is set based on the air conditioner and can quickly and manually set the air outlet mode without causing occupant discomfort.

[Means for Solving the Problem] (Means for Solving the Problems) In order to achieve the above object, the air outlet mode control device for an automobile air conditioner of the present invention is provided with temperature information from various sensors and a set temperature of a room temperature setting means. Based on, and an automatic switching mode that automatically switches the air outlet mode of the air conditioner,

When switching to the mode, transition value setting means for setting the transition value for determining the outlet mode, and the automatic switching based on temperature information regarding the vehicle interior from the various sensors and the set temperature of the room temperature setting means. When the outlet switching switch is turned on in the mode, the switching mode is switched from the automatic switching mode to the manual switching mode while the target outlet temperature calculation means calculates the From the outlet temperature and the transition value set by the transition value setting means, the outlet mode to be switched first when switching to the manual switching mode is calculated and switched to the outlet mode, and thereafter, Each time the blow-out port changeover switch is turned on, it has a blow-out port mode switching means for switching the blow-out port modes in a different order according to the type of the blow-out port mode that was switched first.

(Operation) The present invention configured as described above operates as follows.

Various sensors provided in each part of the vehicle input temperature information relating to air conditioning in the passenger compartment, and an occupant operates an operation switch provided in the passenger compartment, so that the room temperature setting means causes the passenger to request. By inputting the set temperature in the vehicle compartment, the target outlet temperature calculation means calculates the target outlet temperature of the air blown into the vehicle based on these various sensors and the room temperature setting means, and calculates the target outlet temperature. Output to the outlet mode switching means.

Then, the outlet mode switching means, when the outlet switch is first turned on, based on the target outlet temperature,
Set the initial mode of the outlet mode. For example, the outlet mode setting means, when the target temperature is less than the low transition value that is the criterion for transitioning from the vent mode to the bi-level mode, in the vent mode, the low transition value or more,
In addition, when it is less than the high transition value which is the criterion for transitioning from the bi-level mode to the foot mode, the initial mode is set to the bi-level mode and to the foot mode when it is equal to or higher than the high transition value.

After that, each time the outlet switching switch is turned on, the outlet modes are switched in a different order according to the type of the outlet mode switched first.

(Embodiment) Hereinafter, an outlet mode control device for an automobile air conditioner according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an air outlet mode control device according to the present invention. In FIG.
An air outlet mode control device 10 for setting the initial mode of the air outlet mode for manual setting based on the target air outlet temperature when turned on is shown.

The air outlet mode control device 10 is connected with various sensors 11 including an outside air sensor for detecting the outside air temperature, an inside air sensor for detecting the temperature inside the passenger compartment, and a solar radiation sensor for detecting the amount of solar radiation incident on the inside of the passenger compartment. A target outlet temperature calculation unit 13 is provided, and the target outlet temperature calculation unit 13 is capable of inputting temperature information regarding air conditioning in the vehicle compartment through each sensor of the various sensors 11. .

Further, as in the conventional case, the target outlet temperature calculation unit 13 is a room temperature setting device for setting the temperature inside the vehicle compartment by operating the room temperature setting switch provided on the operation switch panel or the like in the vehicle interior. 12 is connected, and the target outlet temperature calculation unit 13 can input the set temperature in the passenger compartment requested by the occupant via the room temperature setting unit 12.

Then, the target blowout temperature calculation unit 13 calculates the optimum target blowout temperature of the air blown into the vehicle compartment based on these temperature information and the set temperature (similar to that performed in a conventional so-called full-auto air conditioner. ), The target outlet temperature is output to the outlet mode setting unit 14.

In addition, the inside air sensor of various sensors 11 and the room temperature setting device 12
Is connected to a transition value setting unit 15 that determines the air-conditioning states of cooling and heating and sets a low transition value and a high transition value that serve as a criterion for setting the initial mode.

The transition value setting unit 15 determines that the air conditioning state is the heating state when the set temperature is equal to or higher than the inside temperature, based on the difference between the temperature inside the vehicle (hereinafter referred to as the inside temperature) and the set temperature. If not, it is determined to be in the cooling state.

Then, as a result of this determination, the transition value setting unit 15 sets the transition value as shown in FIG.

FIG. 2 shows how the outlet mode is set for the target outlet temperature. This is a so-called fully automatic air conditioner, and the outlet mode is automatically set according to the target outlet temperature. Is similar to what is done when setting.

As shown in the figure, the transition values a, b, c, d which are the criteria for transitioning to the respective modes are preset, and based on these transition values, when the target blowout temperature is low, the vent A mode is set, and a bi-level mode is set when the temperature is intermediate and a foot mode is set when the temperature is high.

When the transition value setting unit 15 determines that the air-conditioning state is the heating state, the transition value setting unit 15 sets the transition value between the vent mode and the by-leveling mode (hereinafter, referred to as a low transition value) to a, and the bi-level mode. The transition value between the foot mode and the foot mode (hereinafter referred to as high transition value) is set to b.

The transition value setting unit 15 sets the low transition value to c and the high transition value to d when it determines that the air conditioning state is the cooling state.

Then, the transition value setting unit 15 outputs the low and high transition values set according to the air-conditioning state to the outlet mode setting unit 14.

These low and high transition values, and the outlet mode setting section 14 for inputting the target outlet temperature, are arranged on the operation switch panel or the like in the vehicle compartment as in the conventional case, and automatically set the outlet mode. The blower outlet switch 16 is connected to switch from the automatic setting state to the manual setting state in which the passenger manually sets the blower outlet mode according to his / her preference.The passenger sets the blower outlet mode by turning on the blower outlet switch 16. Part 14
Is designed to set each outlet mode.

The operation switch panel is provided with an auto switch (not shown) for returning the outlet mode to the automatic setting state with respect to the outlet switch 16.
When the occupant turns on this auto switch, the setting of the air outlet mode is switched to automatic setting.

Then, the air outlet mode setting unit 14, the occupant, when trying to manually set the air outlet mode for the automatically set air outlet mode, first turn on the air outlet changeover switch 16. Thus, the initial mode of the outlet mode is set based on the target outlet temperature and the low and high transition values.
For example, if the input target outlet temperature is less than the low transition value, it is in the vent mode, and if it is at least the low transition value, and if it is less than the high transition value, it is in the bi-level mode, the high transition value. In the above cases, the foot mode is set to the initial mode.

Further, when the initial mode is set to the vent mode, the outlet mode setting unit 14 will switch the outlet selection switch thereafter.
Each time 16 is turned on, the outlet mode is set in the order of vent → bilevel → foot. Similarly, when the initial mode is set to bilevel mode, bilevel → vent →
When the initial mode is set to the foot mode in the order of foot, the air outlet mode is set in the order of foot → bi-level → vent, and the mode signal for setting the set air outlet mode is set to the mode door actuator (hereinafter, MA It outputs to 17).

That is, the outlet mode setting unit 14 compares the target outlet temperature calculated by the target outlet temperature calculator 13 with the low and high transition values set by the transition value setting unit 15, and sets the initial mode of the outlet mode. And the outlet selection switch 16 is turned on.
The outlet mode to be switched every time is set in a different order depending on the type of the outlet mode that was switched first, and according to this order, the mode signal is output to the MA17 every time the outlet switch 16 is turned on. It has become.

Then, this MA17, based on this mode signal, the vent outlet of the air conditioner, drives the doors arranged at the respective outlets of the foot outlets to open and close the respective outlets, and the outlet mode, The air outlet mode setting unit 14 sets the air outlet mode.

The air outlet mode control device of the present invention constructed as described above
10 operates based on the flowcharts shown in FIGS.

As shown in FIG. 3, the air outlet mode control device 10 calculates the target air outlet temperature based on the various sensors 11 and the room temperature setting device 12, and sets the transition value according to the current air conditioning state. Then, as shown in FIG. 4, when the outlet switching switch 16 is first turned on, the target outlet temperature is compared with the set transition value to set the initial mode of the outlet mode, and the outlet switching thereafter. Each time the switch 16 is turned on, the outlet mode is switched in a predetermined order, and the outlet mode is set based on the target outlet temperature.

First, the target outlet temperature calculation unit 13 inputs temperature information regarding air conditioning in the vehicle compartment detected by various sensors 11,
The set temperature in the passenger compartment requested by the passenger is input via the room temperature setting device 12. On the other hand, the transition value setting unit 15 inputs the inside temperature by the inside air sensor of the various sensors 11 and inputs the set temperature in the vehicle interior by the room temperature setting device 12 (step 1).

Then, the target outlet temperature calculation unit 31 calculates the target outlet temperature based on the temperature information and the set temperature, and outputs the target outlet temperature to the outlet mode setting unit 14 (step 2).

The transition value setting unit 15 compares the input inside air temperature with the set temperature, and when the inside air temperature is equal to or lower than the set temperature, determines that the current air conditioning state is the heating state, and sets the low transition value to a. The high transition value is set to b. Otherwise, it is determined that the air conditioning state is the cooling state, and the low transition value is c and the high transition value is d.
Set the transition value to the outlet mode setting section.
Output to 14 (steps 3, 4, 5).

Then, the air outlet mode setting unit 14 which has input the target air outlet temperature and the transition value sets the air outlet mode based on the flowchart shown in FIG. 4 (step 6).

In the outlet mode setting unit 14, the outlet switch 16 is turned on.
Wait until the automatic switching mode is switched to the manual switching mode (step 10), and this switch is turned on first.
By doing so, it is judged whether or not the target blowout temperature is smaller than the set low transition value a or c (step 11).

Then, the outlet mode setting unit 14, as a result of this determination,
If the target outlet temperature is less than the low transition value and it is determined that the passenger compartment needs to be relatively low,
The initial mode of the outlet mode is set to the vent mode, a mode signal for setting the outlet to the vent mode is output to the MA17, and the vent mode is formed by the MA17.

Then, similarly, until the auto switch is turned on, the blowout port mode is set in the order of pent → bilevel → foot until the auto switch is turned on, and the mode signal for setting the blowout port mode is set. Output to MA17 to form each outlet mode (steps 12 to 17).

Further, the outlet mode setting unit 14 is in the step 11,
If the target outlet temperature is not lower than the low transition value, it is determined whether the target outlet temperature is at least the low transition value and less than the high transition value (step 18). As a result of this determination, the target outlet temperature is low. If it is determined that the temperature is higher than the transition value and lower than the high transition value, and it is determined that the vehicle interior needs to have an intermediate temperature, the initial mode of the outlet mode is set to the bi-level mode, and the outlet is set to the bi-level mode. A mode signal to be set is output to MA17, and MA17 forms a bilevel mode.

Then, similarly, until the auto switch is turned on, the blowout port mode is set in the order of bi-level → vent → foot every time the changeover switch 16 is turned on, and the mode signal for setting the blowout port mode is set. Output to MA17 to form each outlet mode (steps 19 to 24).

Further, the outlet mode setting unit 14, in step 18, when it is determined that the target outlet temperature is not lower than the low transition value and lower than the high transition value, the target outlet temperature is higher than the high transition value, the interior of the vehicle When it is determined that it is necessary to make the temperature relatively high, the initial mode of the air outlet mode is set to the foot mode, a mode signal for setting the air outlet to the foot mode is output to the MA17, and the MA17 forms the foot mode.

Then, similarly, until the auto switch is turned on, the blowout port mode is set in the order of foot → bilevel → vent until the auto switch is turned on, and the mode signal for setting the blowout port mode is set. Output to MA17 to form each outlet mode (steps 25 to 30).

In this way, by setting the initial mode of the outlet mode on the basis of the target outlet temperature, it is possible to set the initial mode according to the air conditioning state required by the occupant. That is, it becomes possible to set the air outlet mode that the occupant may manually set to the initial mode.

(Effect of the Invention) As is clear from the above description, the present invention has the following effects.

Since the outlet mode switching means sets the outlet mode immediately after being set to the manual switching mode based on the target outlet temperature calculating means, the occupant can select a desired outlet mode with the minimum operation of the outlet switch. The number of times can be set promptly, and when switching from the automatic switching mode to the manual switching mode, unexpected air temperature and air volume do not hit the occupant. There will be no pleasure.

In addition, since the blowout port mode can be set promptly and in the manual switching mode without giving an occupant an uncomfortable feeling, the occupant may take a long time to set the blowout port mode by the manual switching mode. It will disappear and more safe driving will be done.
